Bio-purification and photocatalysis duplex sewage treatment tower

Abstract

The invention discloses a bio-purification and photocatalysis duplex sewage treatment tower, which is characterized by comprising a tower body device, an ecologic filter layer device, a photocatalysis reaction device, a mud separation net and a water inlet / outlet device. The tower body is of a hollow cylindrical structure, the upper end is provided with a top cover, the ecologic filter layer is fixed in the middle of the tower body and is divided into a first filter layer, an ecologic filler ball layer and a second filter layer from top to bottom, which are divided and supported by partition plates; a photocatalysis reaction tank is arranged on the upper part of the ecologic filter layer and is internally provided with multilayered annular photocatalysis water permeable walls and ultraviolet lamp tubes, and the mud separation net is arranged at the lower part of the tower body; a water inlet pipe is arranged at the side wall of the lower part of the tower body; the upper end of a water outlet pipe is connected with the bottom of the photocatalysis reaction tank; an opening in the lower end of the water outlet pipe is formed in the bottom of the tower body. The bio-purification and photocatalysis duplex sewage treatment tower has the advantage that various pollutants in sewage can be effectively removed after duplex treatment of bio-purification and photocatalysis.

Description

technical field [0001] The invention relates to a biological purification and photocatalytic double sewage treatment tower, which belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of my country's industrialization and the further improvement of the degree of agricultural intensification, the generated industrial sewage, agricultural sewage and domestic sewage have caused serious damage to the water environment. A large amount of industrial wastewater is directly discharged into rivers, lakes and other water bodies without treatment. At the same time, excessive application of chemical fertilizers and spraying of highly toxic and high-residue pesticides are also common in farmland, resulting in aggravated agricultural non-point source pollution and eutrophication of water bodies. serious. This leads to the overall deterioration and eutrophication of water bodies in rivers and lakes, and also frequently leads to a seri...

Problems solved by technology

However, due to the limited types of pollutants that microorganisms can decompose and metabolize, the efficiency as a single water purification method is not high, and microorganisms have strict requirements on the living environment, so the scope of application is limited.
